HARRY II. DENT AND CHARLES C. KAISER, OF ALLENTOWN, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 585,260, dated June 29,1897.

Application filed November 25, 1892. Serial No. 453,041. (N0 model.)

To aZZ whom it may concern.-

Be it known that we, HARRY H. DENT and CHARLES C. KAISER, citizens ofthe United States, residing at Allentown, in the county of Lehigh'andState of Pennsylvania, have invented certain new and useful Improvementsin Rim Latch-Locks; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawin gs, and to lettersof reference marked thereon, which form a part of this specification.

The object of our invention is to providea novel rim latch-lockespecially adapted for the doors of refrigerators and which is of asimple construction and very durable when in use, such lock beingprovided with a suspended handle pivotally connected with the face-plateof the casing and can be partially lifted away from the casing for theplacing of the fingers around the handle portion and by a simple pullingaction the handle can be made to operate the latch.

The invention therefore consists, essentially, in the combination, witha latch-lock casing having a bolt or slide therein and an opening in itsface-plate and a latch-dog in said casing, of a drophandle pivotallyattached to the said face-plate, said handle being provided with an armor lift extending through the opening in the face-plate adapted toengage with said latch-dog to operate the same when the drop-handle isworked to open or close the door.

In the drawings herewith accompanying, in which similar letters ofreference are employed to indicate corresponding parts, Figure 1 is aperspective view of a rim latchlock embodying the principle of ourinvention, and Fig. 1 is a similar view of a keeper or nosing used inconnection with the latchlock. Fig. 2 is a perspective view of thelatchlock from the rear of Fig. 1. Fig. 3 is a horizontal section takenon linex in Fig. 2, clearly illustrating the manner of pivoting thedrophandle to the face-plate and showing the arm or lift on said handlein operative engagement with thelatclrdog. Fig. ais a vertical sectiontaken on line y in Fig. 2, illustrating the drophandle and its arm orlift in their normal positions. Fig. 5 is a likesection taken on saidline y in Fig. 2, illustrating the drop-handle in its lifted positionand thearm connected therewith just about to operate the latch-dog.

In said hereinabove-described views, a indicates the face-plate of thelatch-casing having a rim or flange ct, provided with screw holes a forsecuring the latch-casing to the surface of the door.

Within the latch-casing is pivoted the latchdog 0 by means of a screw orpivotal pin Z) in such a manner that its dog 0 projects from the casingand is adapted to engage with a suitable keeper or nosing cl. The saidlatchdog 0 is provided at its opposite end 0 with a suitable tailpiece 0which is preferably ring-shaped, as will be seen more especially fromFig. 2. Said latch-. (log is normally pushed down by means of a suitablespring 6 for the purpose of holding the dog 0' in its proper position toengage with the keeper or nosing d, and beneath the latchdog we havearranged a suitably-constructed slide or bolt f, which can be moved backand forth by means of a key having an arm f, which can be moved above afinger c of the latch-dog, and thereby holding the latter in its lockedposition.

As will be evident from Figs. 1 and 3, the face-plate of thelatch-casing is formed with a pair of outwardly-projecting ears or lugsa between which is pivoted a suitable drophandle g, which is retained inits proper position by the fiat portions g, which normally bear againstthe outer surface of the faceplate. In said face-plate a is formed anopen ing a, as shown in Figs. 3, 4, and 5, through which extends the armor lift 9 formed directly behind one of the pivotal supports 011 saidhandle. Said arm or lift 9 bears normally against the upper and inneredge e of said ring-shaped tailpiece 0 as will be evident from Figs. 2and 4. When the handle 9 is raised to the position indicated in Fig. 5,said arm or lift g passes down against the lower and inner surface a ofsaid ringshaped tailpiece, as shown, and when the handle is pulled upstill farther said arm or lift 9 forces the latch-dog c to assume theoperated position indicated in dotted outline in Fig. 2,

when the tailpiece is depressed, thereby lifting the dog 0' out of itsengagement with the keeper or nosing d and allowing the door to beopened.

Instead of the tailpiece c of the latch-dog being ring-shaped, it isevident that the same may be slotted to permit the movement of the liftg therein.

One of the principal and most essential features of the presentinvention is the construction of the latch-dog provided at or near itsinner end with the perforation or ring-shaped tailpiece 0 into which thearm or lift g extends, whereby this great advantage is derived that thelatch-dog or bolt can be operated by both motions of lifting andpressing down of the handle g. Thus in closing the door the handlenecessarily is pressed down, and should the latch-clog c bind againstthe nosing or keeper d on account of the swelling of the door, when thespring e would not be of sufficient strength to force the dog 0' down toits locked position in the nosing or keeper, said latch-dog or bolt isforced down by the pressure on the handle 9, its finger or lift 9thereby being caused to act as a lever within the ring-shaped tailpiecec to force the end 0 of the bolt upward and the dog 0 down into itslocked or holding position within the nosing, as will be clearlyunderstood.

Another feature of this construction is that the door of a refrigeratoror other compartment can thus be firmly closed and forced against thedoor-frame and made to bind airtight.

The arm or lift g may also be differently constructed, as will beunderstood, and we therefore do not limit ourselves to the exactconstruction and arrangements of parts herein shown, the essentialfeatures of the inven tion being an arm or lift on a pivoted handle,said arm or lift extending through an opening in the face-plate of thelatch-lock and engaging with the tailpiece of a latchdog, whereby thelatter operates when the drop-handle is either raised or forced down.

Having thus described our invention, what we claim is 1. A latch pivotedwithin a casing and a drop-handle pivoted on the outer side of thecasing and provided with an extension projecting into the casing and inpositive engagement with the latch, whereby the latchmay be operated ineither direction by the handle, substantially as described.

2. A latch pivoted within a casing and a drop-handle pivoted on theouter side of the casing and provided with latch-operating means formedon and projecting from said handle so as to enter the casing anddirectly engage the latch, whereby the latch may be operated in eitherdirection when the handle is raised or lowered, substantially asdescribed.

3. In a combined latch and look, a latch pivoted within a casing, aleaf-springin engagement with and adapted to actuate one end of thelatch, and a drop-handle pivoted on the outer side of the casing andprovided with an integral extension projecting into the casing and inpositive engagement with the latch, whereby should the spring becomeinoperative the latch can be both depressed and elevated by means of thehandle, substantially as described.

4. In a combined latch and look, a latch pivoted within a casing, apivoted drop-handle adapted to operate the latch in either direction,said handle being provided with an integral extension in positiveengagementwith the latch, a spring for operating the latch in onedirection independent of the handle, a keeper with which the latchengages and a locking-dog adapted to be moved to lock the latch,substantially as described.

5. In a combined latch and lock, the combination with a latch pivotedwithin a casing and a drophandle adapted to operate the latch in eitherdirection, said handle being pivoted on the outer side of the casing andprovided with an integral extension projecting into the casing and inpositive engagement with one end of the latch, of a locking-dog adaptedto be moved within the easing into such position that it will render thelatch immovable, substantially as described.

In testimony that we claim the invention set forth above We havehereunto set our hands this 21st day of November, 1892.
